Hours before voters were due to head to the polls, Republican businessman Gabriel Gomez of Cohasset and U.S. Rep. Edward Markey of Malden were busy rounding up last minute support at campaign events Monday.

Markey targeted western and central Massachusetts on the final full day of campaigning, visiting supporters in Springfield and Worcester in addition to going on a business tour of downtown Lawrence before holding a rally in his hometown of Malden.

Gomez visited voters across Southeastern Massachusetts greeting morning commuters at Braintree’s MBTA station before holding events in Brockton, Hingham, Plymouth, and Hyannis. Gomez concluded his campaign stops on Monday with a rally with former U.S. Senator Scott Brown, R-Mass., in Quincy.

A Suffolk University poll released on Monday showed that Markey has a 10-point lead over Gomez, 52 percent to 42 percent going into the election that will replace former U.S. Sen. John Kerry, D-Mass.

Despite trailing in the polls, Gomez expressed confidence to his supporters during a campaign event with State Sen. Robert Hedlund, R-Weymouth, at Hedlund’s restaurant Four Square in Braintree.

“I couldn’t feel better about where we are,” said Gomez. “We’re going to make history tomorrow.”

Gomez talked about the lengths that the Markey campaign has gone to try to defeat him, including events with President Barack Obama, Vice President Joe Biden, and former-president Bill Clinton.

“Obviously, they’ve had to throw the kitchen sink at me, and we’re in striking distance here, “Gomez said.

Markey was also galvanizing supporters.

“This is what the first five months have been all about,” Markey told supporters on Sunday.

Massachusetts Secretary of State William Galvin is estimating that no more than 1.6 million voters, 37 percent of the state’s 4.3 million total will vote.

Polls will open across Massachusetts at 7 a.m. Tuesday, and they will close at 8 p.m.
